ing is a specification.

In vconliection,withthe walls of railway' box-cars it is desirable toprovide some simple and efective means. for maintaining.

` .tight the joints or seams between the boards or planks, especiallywhen the wall is com`- posedof but a `single `tlfiiclrness' of suchboards. it is well 'known' that-suchjboards or planks have a tendency toshrink, diminishing .their transverse dimension, and obviouslyvwhere buta single thickness of such boards is used in a car-body wall some tightwise a lading' composed of small particles, such as grain, would leak,and the outer air and moisture would have a. more or less freepresentinvention is to provide an econom ical and efficient, means foraccomplishing such a result.

Several desirable embodiments of the invention, have been illustrated'in the accompanying drawings which form a part of this. specificationand throughout the various views of which like reference charactersrefor to the same parte.

in Figs. Band 9; and Fig. ll is a cross-sec tion through a car-side,showings/,till another style or form of tightening means. As is usual incar-body constructions, th

car .has the ordinary channel center-sills 2G,

20, channel side-si`lls2i, 2i, to the outer.

faces of which` are riveted the lower ends oi vertical posts 22 Iand 23,which. may be of any of the ordinary forms of sections,

Vdiagonal braces 24; being also riveted or otherwise asteneal to theside sills. At the tops .of the'car-body sides I position a pair of roofbeams 25, 25, which may, it desired, be of channel shape, the upper endsoi' the .posts 22 and 23 and the braces being riveted or bolted theretofor an object per fectly obvious. v

Each car-side is composed of a pluraiity of boards or planks 26, tonguedand grooved in any approved manner, and securedto the inner faces or'the outer posts and braces 22, 23 and '24 by means of indicated in Fig.3, passthroughgsmal slots 28 in the flanges of these" outer metallicmembers. The top board or plank, 26 has dis posed on its upper edge a.metallic strap or bolts 27, which as is'` bar 29,1 with which the lowerends of a plurality of tightening screws 30 coast, such screws passingthrough threaded holes in.v the lower inwardly projecting flanges ofthe,

channel' roof-beams 25. It will therefore be obvious that if thejointsor seams between theboards have a tendencyto open up, due

to the shrinkage or' the lumber, they may be tightenedby .loosening thebolts 27, turning the screws 30 so as to bring vertical pressure to bearupon the boards and then ti btf eningthe bolts 27 to hold the boardsaint ieir` new relation. in order to prevent the en? posure of the screws30 Aand other parte to theelernents, l fasten to the outer face of eachrooibeani a. metallic apron or .shield`32, whiohprojects downwardly soas to overlap 'the top board, as is shown in Fig. Ai. Also,

in order to strenothentheflange 3l, the beam 25 may be providedwith aplurality cia strap braces 33 rivetedat their upper ends ati to the webof the beam, and at' their lower ends'at 35 to the beam flange. Thesebraces may or may not beused, as occasion. dief mande, and for thatreason they `are vnot showninFigQ. l Reterrin now to Figs. 5 to 7,inclusive, it

iet."

-will be Vnoticed that the construction is eizvactly the same asthat--ofFigsl`to`4,

clusive, eXcept with respectvto the apron Vori metallic shiel'd 32,which in this new embodiment is replaced by a substantially invertedU-shaped member 36 riveted tothe lower face of the bottom flange of beam25 and straddlingthe top yboard or\ plank 26, its opposite marginal-flanges overlapping s uch board, as is clearly indicate'din Fig. 7. In-

stead of using' a .longitudinal bar 29 von the top edge'oftheupperboard, washers or on the top-edge .ofthe upper `-board I26, andextends upwardlythrough 'a hole 40 in the lower flange 4 1 ofa'channel.roof beam-42 the hole Ibeingslightly larger than the screw,

.small plates 37 may be employed to prevent the lower end of the screwfrom ineffectively pressing vinto the comparatively .soft wood.

Looking nowat Figs. 8 to IQ-inclusive, it willbe observed thateach screwy38 bears at its lower end on vva blockerplate 39 disposed asis clearlyshown, Riveted at 43 tothe outer face of-,beam 42 is a depending apron,o'r

I b ack depending wall 50 n adapted to bear.

shield: 44,l which may-be y inwardly bent sli htlyat 45, if desired, andon the screw 381 be ow the flange '4l I employ an angular. nut 46,`through thej screwftlireaded aperture of whichthe screw48 passes. Itwill therefore be apparei'it that las 'the screw 3 8 is turned by meansof a wrenchapplied toits squarehead V47, pressure is brought to bearonthe boards' ofthe side-wall 'so as'to'close the joints be tween'them. Inthis instance' the screw.-

threaded'.liol'e' .of`the nut or blockl 46'is em? ploye'd for thistightening effect ratherthan `using.' a screw-threaded aperture in theflange ofthe roof-beam, and by employin a block 4 6jof desired thicknessan vunusual yl strongand veffective a plian'ce of this character can oprevent thescrewg 38 from acmdentally turning, I "may use 'alockiiig" berovided.-

member 48 having a top wall 49adapted to reston the top of the screwand-having 'a -a ainst the inner face ofthe beam 42, and aso having twoside walls/51 intended to straddle the screw-head so as to prevent itsunintentional turning. To remove this screw-lock so as to permit'rotation of the screw, it' is merelyraised, from which elevatedposition it can be readily taken out of place-5 "and to applyitin-e'ective engage- 'ment with the'screw-head, it-is merelynecespreviousinstances, vif -desired, by a saryfto' slip-it over suchhead into the positionV of Fig. .9. In this instance the flange 49 maybe braced and strengthened as in the lurality of strap braces 51, anynumber of Iwliiich may be employed, vpreferably adjacent to thcscrew, asshown in Fig. 8.

Another Wa of arrivmg 'at substantially the same regu t is indicated inFig, 1l, in which casethe channel-beam'52 hasriveted thereto an outsideapron' 53, bent as shown so' as to overlie both' the bottom and uppervfaces of the screw. 55 has fitsthreads coa'cting with thethreadedaperture extended not only throughthe flange :54, .'but alsothrough the two thick-I nessesl of the apron 53 which straddle the`number of lthreads-for the proper engagement '70 ilangefL In this way ahole with a sufficientV` of the screw is readily secured, the bottom endof such screw, as vinthe previous instance, bearing on a metallic strap5G on' the top edge of the upper board 2G, or, if found more feasible,this strap may be replaced by metallic blocks, as shownin 'F ig.- 9, forinstance.

In all these species it will .be observed that by tightening thescrewsprovidcd for that purpose the shrinkage in .theboards` may becompensated for so as to keep the walls, either side or-end, of thecar-bodyclosed. It will to produce, simple in construction andreadilyo'perated. By using a considerable num-v ber ,of such screwsthroughout t ie length of thecar, as shown in Fig.- 1,'any inequalitiesreadily overcome because of the-individual adjustments which the screwsmaybe given.

- This invention, as will be readily understood by those skilled in theart, is suscepftible .of a considerable number of embodi ments, and forthat reason I do not wish to vhave it understood that the invention isl-iniited to the precise embodiments herein indicated.
